[Q] Verizon LG G2 Stuck in CWM Bootloop - Verizon LG G2

Hey guys,
I accidentally selected the OTA that popped up on my phone while on a Stock ROM and now my Verizon LG G2 is stuck in a bootloop with CWM Recovery 6.0.4.4 I have tried to wipe everything and install a older CM ROM and Gummy ROM to see if that would get my phone to turn back on and it doesn't. I have researched many threads to see if there was a resolution for my issue, but everything that I tried did not work. I have a iMac and a Windows laptop and I have tried many things with Terminal and Command Prompt and nothing seems to work. I don't know if I am doing something wrong with ADB or if I am simply just missing other things, but I am trying to get my phone back un-rooted and back to stock to get my phone replaced under the warranty. PLEASE HELP!

Try the LG tools for bricked G2. Its somewhere on these forums. All you have to do is plug up to a computer and flash the stock ROM with the tool.

I tried the LG Flash Tool on a PC, but it gives me an error message LG USB/Parallel Lock Key is not detected and when I hit OK, it pops up with a Login with the Country filled in with Republic of Korea, ID and Password are left empty. I don't know what to do from there.

Enter into download mode by turning off your phone, then hold vol + and plug it to your computer.
Download the official firmware for your device.
Download FlashTool.1.0.54
unzip FlashTool.1.0.54, open the folder and launch UpTestEX.exe
Select type:3GQCT
Phone mode: DIAG
Select kdz file: browse for your official firmware
Then click: normal web upgrade test
Then click: Upgrade start
a new window will show, chose english language. Country: korea, then click ok and wait untill the firmware installs.
Good luck.

How can I flash TWRP when my phone won't boot? According to a post I read and a YouTube video tutorial I watched, they keep referring to turning on USB Debugging which I can not do.

HELP!!! Please! BRICKED!!!

Hey so I have the L90 D415 and I flashed the partition tool to get more data but i didn't realize that it was broken for my device and now im having issues.... This is how it went. I used the tool and it got to 70% and rebooted back into twrp so i knew that wasnt right so i flashed the next one that was supposed to be fixed and it did flash completely but for some reason it erased twrp, installed cwm and now i cant get into either. I had flashed stock using cwm before i chose to reboot but im still not able to boot up(stuck on LG logo). So to recap I can't get into recovery at all. I have fastboot. flashtool wont work(wont read phone in usb mode cuz im not booted) and im stuck on the LG boot screen. Please help me.

Well duh you didnt wipe the data of the rom before you flashed so of couse you are gonna be boot. Flash with the kdz offline flash then when you are done flashing pull out battery and use special button combo to factory reset it so that you can boot in to phone but you will lose all data excluding the ones on your EXTERNAL sd card.

What do you mean by offline flash?(sorry first LG. I had a Huawei before this)

You need to make sure that you have hidden files on
yeah i figured it out with google.
I have tried both methods on the guide and have came up short both times. I keep receiving this error(In screenshot).
I am desperate for any fix to this problem. I have access to fastboot and download mode. That is honestly all i got. When my phone is on the LG screen my computer reads it but the lg flash tool has connection issues. Please help me figure this out. I really need my phone back.

Go on the lg website and find lg l90 d415 drivers and install them if you got that far its most likely just driver issues.

Also check if you have your computer enabled for all drivers..
Some drivers do not boot because the certificate is not correctly assigned.
If you have a PC running Windows, on boot press F8 and select disable driver certification verify.
Try again after this.

then it goes to this screen (see image)
i can press up to go to download mode
and the pc is reading it as a serial port but the LG flash tool 2014 is not flashing it keeps failing to connect to the server or failing outright with the option to EXIT
i did download the VS980 kdz file
so im not sure how to move from here or if the phone can be recovered at all

It your getting "network error" on the kdz method that's normal.. If you move the window you'll see that it's actually flashing.
I'll help you out in my guide you posted in

Well bro I was stuck with the same issue..
This happens to me when i flashed a wrong twrp recovery for lg g2 d801 and it was stuck in critical error i was also unable to access download mode ..
But my Good luck was that i recovered it by doing silly thing ?
So i do following things. But make sure u know the corrert version of your lg g2 to flash kdz file with lg flash tool and also must have lg drivers intalled.
Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode

It happened to me several times. You should be able to boot into system though. If you kept a backup of your stock recovery, you can restore it and resolve this issue immediately.

Got OTA update but stil in 4.4w1

Hello,
I have my G watch R for a week and because there was no update, i've tried to install it by myself after reading some posts on XDA.
I've tried that :
- Enter Bootloader (swipe top left-bottom right as soon as the LG logo pops up on boot)
- Unlock bootloader (fastboot oem unlock) and boot the watch normally once
- Turn off and re-enter bootloader
- Flash 5.0.1 Stock Recovery (fastboot flash recovery filename.img)
- Enter recovery and ADB sideload the update (tap the android, select install update from ADB and enter adb sideload filename.zip)
All this works until the "sideload" part because ADB can't see my watch when it's on recovery mode.
So i have locked again the bootloader and i thought to give up, when yesterday, OTA arrived...
But it hasn't worked : a bar has loaded and it arrived on a red triangle with an exclamation mark, i've clicked on it and i had the recovery mode menu (reboot, install from adb, etc)
What can I do to make work this OTA ?
Thanx for help !
have you tried to flash the original recovery?
Yes, I've tried several times, I think that is why i can't update with OTA.
But is there a solution ? Is it possible to reinstall original recovery and will it solve my problem ?
Or must I install the update with ADB ? Because I still don't know how make the watch recognized when in recovery mode (not even recognized with a yellow triangle, like it was unplugged )
I had the same problem but with 4.4w.2 and I solved it flashing the stock recovery. unfortunately I can not find your recovery version, I would have linked. to manually update do not know ... I'm sorry. Find your recovery and flash it!
Thanx for your answer,
I thought to do that, but I neither have found 44w1 stock, i'm trying with 44w2 stock and it doesn't work.
I'll try to find 44w1 stock, thanx for confirmation about this way.
So, while I can't find 44w1 stock (i think nobody has uploaded it on the internet because nobody wants to put 44w1 on his watch ^^ ), I've tried TWRP Recovery
When I try to launch the 5.5.1 zip install , I have this error message on the watch in TWRP Recovery :
"this package is for device: lenok. this device is dory"
I've made some research and found that Dory is for G Watch and not for G Watch R, so what ?
I don't understand...
Anyway, if someone knows where to find 44w1 stock...
Did you enabled the debugging mode and gave permission for it on the watch?
sounds like you are missing the ADB drivers on your PC
and be careful with sideloading the update to select the correct one, e.g. the last update is an incremental one and won't flash on 4.4 (or if you get it to flash, it will probably not worke)
good luck!
Have a look here... http://4pda.ru/forum/lofiversion/index.php?t647135-20.html.
It's not English, but the links are all there. I recently updated a watch from 4.4 to 5.11 using these images. Put the watch into Bootloader and install the ADB drivers, then start with 4.4w2 and work your way up. It takes time as you'll need to restart the watch each time.

No I'm not, same answer : I could flash a recovery without any problem : it's only when I'm on recovery that I can't communicate with the watch : It's working when android wear is started and when I'm on bootload. Thanx for the warning

Thank you but i have all those images, I think I need 44w1 recovery and only this one
Thank you all
what happens if you just flash the 4.4w2 full image? I remember there being issues with the 4.4 recovery and I had to manually update to the 5.0.1 recovery before then upgrading further.
edit...what drivers are you using? I think you need the adb composite ones and not the normal adb ones.
I'm using the naked ones I think.
What image are you talking about ? System or recovery ?

flashing a recovery happens in fastboot mode, which requires an unlocked bootloader, but not enabling the debugging mode
sideloading however happens (once the recovery has been loaded) through ADB - and ADB requires the right drivers on your PC as well as the right tools/developer environment
try to connect your normally booted watch to your PC and run
PHP:
adb devices
if that lists your watch, you are good to go, otherwise ADB isn't set up properly
The watch is listed by adb devices when on work mode or in bootloader mode, but not when in recovery mode.
That's what I said first

Either I can't if with 44w2 recovery, or it says ""this package is for device: lenok. this device is dory" if with TWRP recovery.

Do you have the G Watch R (round) or the G Watch (Square)?
"The watch is listed by adb devices when on work mode or in bootloader mode, but not when in recovery mode."
I had this problem too. When you're in recovery mode you have to open the windows device manager and windows should tell you something about an uninstalled driver. You need to right click this device and install the adb drivers.

Can someone PLEASE help me boot my phone into FASTBOOT mode? ( T mobile h811) on CM13

When I first purchased this phone I was able to boot to the default recovery that came with the phone ( which clearly had a *fastboot option*), it came with stock 5.1, and a bunch of bloatware.
I downloaded the one click root method for the h811 which was perhaps the easiest root i've ever done. great. i also had to flash my recovery to twrp 2.8 for some reason.
Rocked out to a newely rooted device on 5.1 until the t mobile bloatware and system update notification kept bugging me, so I said * eff it, i've been holding out for a while*
So I get to the cm 13 wiki for my device, I managed to install the cm recovery ( cant remember how i did this for some reason) and then i was able to flash cm13 to my phone. CM13 is sleek, and smooth but is presenting problems.
First of all, no google play store and the gapps zip wont install through cm recovery ( fails and tells me to use twrp instead which is a problem because i can't boot this phone into fastboot mode)
I am unrooted and can not figure out how to properly root a T mobile h811 running cm13, so the twrp manager doesn't work because it "requires root" then shuts down. ( enable root access in the cm13 developer options does nothing at all and yes, for adb and apps)
FAST BOOT MODE DOES NOT SEEM TO EXIST ANYMORE ON MY PHONE - Following the many tutorials, which goes long the lines of using adb/fastboot, adb devices can see my device, but fastboot devices can't ( figures) because its not in fastboot mode. Any fast boot reboot bootloader or any variant of that command only reboots the phone, to... swipe the screen.
I've installed the lg bridge crap ( which installed an updated usb driver) that doesn't even recognize my phone " no mobile device connected". tried uninstalling and reinstalling, but nothing. When putting the phone in download mode, to see if adb would rcognize it, windows sees this as a new device , installs drivers but says " device can not start, code 10 * in device manager. :silly:
is there anything that can be done?? google searches result in obvious solutions that SHOULD work but don't, or threads where a person coincidentally has the same exact problem as I do, but their response is usually the last response in the thread that goes unanswered
summary : I've install cm13 on my lg g4 h811, I do not have root access, I can not install twrp due to ( no fastboot mode) in effect, i cant install gapps, cant root phone etc..
any help?
did you ever unlock the phone....?
Yes, unlocking the phone is one of the first things you would need to do. In Developer Options > OEM Unlock. Then in bootloader, run the unlock command. This will delete /data and internal storage so back up your files so you can transfer them back via adb or fastboot.
Then you're probably going to need to temp boot TWRP, then flash the TWRP recovery image in TWRP. THEN you can flash properly.
Carefully read through this thread:
http://forum.xda-developers.com/tmobile-g4/development/stock-h811-20i-images-kdz-flashable-t3308227
Good luck.
Edit: oh and this thread belongs in Q&A.
Alright. Am I only to read the first post or all 30+ pages? ( not that i have a problem, just curious)
Reeeeaaadd ittt alllll! Just kidding. The first post should be fine. You'll be looking at doing everything after flashing the kdz. If you think you've messed up your partitions, flash the kdz and start over.

"ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it."
didn't work, very frustrating. any clues? on windows 8.1 by the way. tried two computers. none can see this phone. I can connect the phone to the computer and see its storage, lg usb driver is installed
You probably need to reinstall the drivers. It might be the fastboot driver. That's what worked for me.
I've reinstalled the official drivers, uninstalled them... Jusst the mobile USB driver, a combo of both, plenty of times. Don't understand why this software doesn't see my phone
Lgup, lgair, lg bridge, lg USB driver (skinned down) .. Nothing works tested on my gaming rig., and work laptop both running win 8.1 64 bit

This section does get more views though haha.
Anyway I feel that the 811 is one of the more finicky devices to get into fastboot at least in my experience. I had to enable and disable dev options while plugging and unplugging device and it finally worked. No idea if that'll work for everyone though.
I reasked the question in Q and A. Please help some one.
You start over. LG bridge.
Having the same issue. I'm on Windows 10. What developer settings did you mess with to get it working, tiskewlio?
The issue i seem to be having is that when I put the device in download mode ( didnt know that is the same as fastboot) drivers attempt to install, "LGE MTP USB DEVICE" has a yellow exclamation mark with a code 10-device cannot start error message. I believe this the issue as any fastboot command stuff says " waiting for any device" . must not yet see the mtp driver .. Also noticed the bridge app immeditaley tries to pick up my device in download mode but fails due to this problem..
Any clues?

silly question maybe, but is there a specific tutorial in getting this to work with the files provided given my situation? (commands, etc..) will this somehow bypass the the lge mobile mtp device that wont install ? I had installed the system wide adb/fastboot drivers, and already had a folder with just the minimal install of the adb but didnt have a few files in the one you provided ( lg root, busy box, etc) so not quite sure what to do with them.
Again, if possible want to flash twrp recovery to my device but can't due to * waiting for any device* and the ( device cannot start ) error
Thanks
* waiting for device* when putting phone in download mode and pushing fastboot flash twrp-2.8.7.1-h811.img.
Any help would be appreciated as I need to get the driver to work first. see attached picture.
Cha h
the issue is largly resolved as i've been able to flash the recovery and install another rom. But i'd still like to know how to get the download mode driver properly working in the event i need a computer and can't do a self contained install.
Uninstall all drivers. Reboot computer. Reinstall latest drivers and LG bridge. Reboot. Then start your process. It'll work. Trust me. Find my posts in primes stock thread. I ran into this issue myself. And if you get an error after flashing where it won't mount /data, that's because it got corrupted. Once in twrp, format /data then reboot to recovery. All will be well to flash. Just a heads up since that was also a problem.

i dont know man, i did all that a million times over, but recently i was able to just flash the stock MM rom to the device using LGup. Think i'll just stick with stock rom and root for a while as all this stuff is a little finicky at times. Thanks for your help.

LG L Fino D290n makes error on boot.No download mode or recovery,please help!

Yesterday a LG L Fino was brought to me for repair.It makes an error on boot.The error is the boot certificate verify error.I cannot fix this!
I tried booting in recovery,gives me the boot screen,then the error,black screen.
I tried download mode,same.
I even tried flashing it,but LG Flash Tool does not recognize it.When i connect the phone a whole alphabet of drives would appear with LG Logos on them.I was able to only open one of them,the size was 64MB and it stored a image folder.Device manager recognizes the phone as QHSUSB_BULK and a ton of Unknown Devices would appear,after that they disappear and the phone will be recognized as LGE AndroidNet USB Serial Port(COM4).Thank you :angel:

And I faced the same issue after a bad flash.
Did you flash anything?
Does the LG logo show up?
Please answer the above questions so I would be able to solve your problem

Hello sir!
I have never flash the phone. The first problem that I have seen was after one restart, it won't boot the os, I have seen the LG logo and after that it keeps reboots again. I have entered in recovery mode and wipe all data, but it didn't help. After that I started to see the message above(error) and that's all. My battery is completely empty and cannot charge it because the phone doesn't charge.

Hey there did you use advanced wipe to clear your data or was it factory reset.
If the LG Logo shows up and then the error comes then you can enter download mode by switching off the phone and then hold volume up key and at the same time insert a usb. You would enter download mode. If you enter the mode you can flash a KDZ

Or If you want custom rom only,enter into recovery mode.
Then click wipe and then advanced wipe.
Check data
Check System
Check Dalvik/art
Check Cache.
And then Press install and download the suitable rom for you phone.
If you cannot resolve the problem contact me again

No, they didn't use advanced wipe because they don't have a custom recovery installed. If you read their post more carefully, you'll see where they said that they never flashed the device, this means they have stock recovery, not custom recovery. None of what you posted helps them.

Hey there thank for informing me.
He can still enter into download mode and flash kdz using flash tool
Custom Rom cannot be flashed
But a stock rom can be flashed and can be fixed.
Its a soft brick so he can surely flash a stock rom and recover his phone :fingers-crossed:\
When you try to charge your phone it doesn't show the charging status
But when you completely drain your battery to 0% it will show 0% and shows charging and you can confirm that it is charging

Did you try to flash a stock update using TWRP?
If so, that is the problem. Stock updates can't be applied to a rooted device or a device that has TWRP installed, any one or both of these will interfere with applying the update. You can only apply stock updates to devices that have an unmodified system partition(no root, no Xposed) and have stock recovery, stock recovery is required for applying stock updates.
If this is what you did, your only option to fix this is to flash your full stock firmware. Do a Google search for:
"Return to stock (your model number)"
If the tools and files exist for your device, that should find it.
